Numerous Encore networks and Al Gore's Current TV are also among the networks that could go on the chopping block, according to a notice published on Time Warner Cable's website.

"Time Warner Cable’s agreements with programmers and broadcasters to carry their services and stations routinely expire from time to time. We are usually able to obtain renewals or extensions of such agreements, but in order to comply with applicable regulations, we must inform you when an agreement is about to expire," the notice reads. "The following agreements are due to expire soon, and we may be required to cease carriage of one or more of these services/stations in the near future."

On New Year's Eve, Time Warner Cable decided to drop the arts-centric network Ovation along with its HD channel. The carrier did, however, strike a long-term deal with Crown Media Family Networks to continue carrying the Hallmark Channel and Hallmark Movie Channel. Time Warner also forged a short-term agreement with AMC Networks to keep airing AMC's IFC and WE tv, while the two companies continue to hammer out a more permanent pact for those networks.
